Helen Mirren has turned back time in her latest L'Oreal Paris campaign and proved she's still defying the years aged 69.

The legendary actress is the face of the beauty company's new Excellence Age Perfect advert and stuns in a series of close-up shots.

The advert, which airs today, sees the star smile at her fans in a white suit and minimal make-up, proving she's well and truly still got it.

According to the brand, she embodies "the perfect balance of smart wit, assured beauty, and drive at any age."

The new brand is formulated for grey hair, and she is undoubtedly the perfect face for the new campaign.

In the advert she says: "You know that moment when you realise what used to work for you, just isn't working anymore? Especially our hair colour."

She adds: "It's taken over 60 years to look this good. We are so worth it."

Helen told the Mail Online during filming: "I used to worry a lot more about my looks than I do now.

"I think the great advantage of getting older is that you let go of certain things. Having said that, I think all women worry to some degree — and I don’t think men are exempt.

"I don’t really like the word 'beauty'. There are physically beautiful people in the world (David Beckham, for instance, is unbelievably beautiful), then there are other people that are not beautiful, but are very attractive because of their personality, energy, brilliance, genius: all kinds of things."
